i have just spent a few hours trying to change the door handles and locks on my defender 110. have managed to get the old push button door handle off and a new one on. and this is where the trouble started. the key barrel is in and the rods are all connected. it looks ok. But when i lock with the key, it works but it unlocks before releasing the key. the mechanism has not been changed just the handle and key barrel. and yes i have been using the new key and not the old one before i ger any sarcastic replies. if anyone has any ideas i'd appreciate the help.
